It has long been known that these conditions, depression and alcoholism, often go hand in hand. Those suffering from both conditions must find addiction treatment centers that treat co-occurring disorders. With new evidence on the role inflammation plays in depression and alcoholism, therapies can improve further to offer effective treatment for alcoholism and depression. So, is inflammation to blame?
Studies show that inflammation in the brain and body can cause depression, and it can also increase the likelihood that someone will drink alcohol in excess. In turn, alcoholism and depression can increase inflammation in the brain, thus reinforcing the challenges. 
Scientists have studied the innerworkings of depression and found that inflammatory responses in the brain can lead to symptoms of depression. Early childhood trauma may increase a person’s inflammatory responses to challenges and increase the likelihood of depression. This is believed to be connected to survival techniques in early humans, and these techniques simply aren’t needed in today’s sanitary and relatively illness-free world. 
Still, the inflammatory responses are present in many people, and as the addiction and alcoholism get worse, the inflammation can also get worse, which may feed into depression. While inflammation alone is not the sole cause of depression, there is a growing understanding of how it can aggravate the condition.
